Application filed mic a,

To all whom it may concern:

Be it known that I, JOHN M. ABRAMS, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Electric- Light Fixtures, of which the following is a specification. v

The invention relates to an improved fixture for electric lamps, more-especially of the miniature type, and designed for use generally in connection with dry cells. It has for its object to provide a fixtureof this type which may be readily and quickly attached to and be carried by a dry cell of the usual well-known type, and which fixture shall be simple in construction and in- The novel fixture, moreover, is of such dimensions and construction that, when not in use, it may be conveniently stored or pocketed and, also, may be economically shippedafiording a A further object of the invention is -to eliminate all switching and like devices in connection with a fixture of this type, the electric circuit for operating the lamp to be carried thereby being established directly by one of preferably, by the nut working thereon.

The nature of the invention, however, will best be understood when described in connection with the accompanying drawings, in which- Fig. 1 is a side elevation of a portion of a dry cell with the novel fixture attached, with circuit to the lamp carried thereby shown open.

Fig.2 is a vertical section thru the fixture, and shows also th circuit to the lamp closed.

Fig. 3 is a plan of the cell with fixture attached; and Fig. 4 is an end view of the latter.

.Figs. 5 and 6 are respectively a side and rear elevation of the fixture equipped with reflector.

Referring to the drawings, 10 designates cell of ordinary construction and provided with the usual threaded terminals as the binding posts 11 and 12 upon which are mounted nuts 13 and 14 respectively, ordinarily employed to secure conductors to the terminals.

In the present instance, however, one of these terminals, as the terminal 12, is designed to carry the novel fixture 15 as by se- 1924. Serial No. 717,492.

curing perforated end 16 thereof in screwing down the nut 14 thereon. The bracket proper extends substantially at right angles from the flattened end 16. and then outwardly parallel thereto so as to be displacedfrom the upper surface of the cell 10; and at its outer en is curved sufiicientl'y to provide a cylindrical receptacle or socketv 17 This socket is provided with pressed threads to receive .the base of a lamp 18, as is well understood,

and is to be so positioned relatively to the terminal 11 as to be substantially coaxial therewith. The lower end of the socket 17 however, is left 0 'n, so that by screwing down the lamp su ciently its contact int 19 may be caused to project beyon the lower edge of the socket ortion 17 of the bracket, the base of the amp constitutin the other place of contact as is the genera practice. Thru the bracket 15, the socket is thus also in contact vwith one of the terminals, as terminal 12 of the cell 10.

In order to closethe circuitto the lamp, contact must, therefore, be established be tween the terminal 11 and the contact point 19 of the lamp; and this may be effected directly, as thru forcing downwardly the socket end of'bracket '15 which is of a more or less resilient nature; It is preferred, however,'to establish the contact by: means of the nut 13, adjustably mounted on the threaded terminal 11, as in turning said surface connut upwardly until its upper point 19 of tacts with the projectin contact the lamp. Since themore or less resilient, an appreciable tension may be secured by screwing up the nut 13 sufficiently; and this will serve to insure good contact between its said upper racket 15 is made thereto the flattened bent-over and near the socket 17. The cylindrical form of this socket may also be conveniently insured by means of a further spur 23 which pojects therefrom to extend thru a slot 24 o the Wall of said bracket. The construcother place of contact makes electrical connection directly with the bracket itself and thereby with the first-named terminal.

I claim 1. An electric light fixture of the character set forth, comprising a bracket'member consisting'of a flat metal strip, substantially rigid and perforated at one end for attach ment to one terminal of a dry cell, said strip being inclined upwardly and brought into a vertical plane by a quarter twist, the other end of the strip being bent around to'provide a socket for receiving a lamp, the socket being adjacent to the cooperating terminal of the dry cell, whereby contact may be established between a lamp terminal and the corresponding cell terminal.

' 2. An electric light fixture of the charac-' ter set forth, comprising a bracket member consisting of a flat metal strip, substantially rigid and perforated at one end for attachment to one terminal of adry cell, said strip being'inclined upwardly and brought into a vertical plane by a quarter twist, and the opposite end of the strip being threaded and having a spur extending therefrom to fit thru a slot of the strip when, bent around in a horizontal plane and providing thereby a cylindrical threaded socket for receiving a lamp, the socket being adjacent to the cooperating terminal of the dry cell, whereby contact may be established between a lamp terminal and the corresponding cell terminal.

3. An electric light fixture of the character set forth, comprising a bracketmember consisting of a flat metal strip, substantially rigid and perforated at one end for attachment to one terminal of a dry cell, said strip being inclined upwardly and brought into a Vertical plane by a quarter twist, the other end of the strip being bent around to provide a socket for receiving a lamp, the socket being adjacent to the cooperating terminal of the dry cell, whereby contact may be established between a lamp terminal and the corresponding cell terminal, and a refiector mounted upon the vertically disposed portion of the bracket behind said socket portion. v
